ATTACH FITTINGS
1. DESCRIPTION
Wing loads are transferred to the fuselage through four wing-attach points, two which are located under
each front seat and the remaining two on either sidewall just aft of the rear seats. The forward attach points
transfer load into the spar tunnel. The aft attach points transfer load into the fuselage skin and aft floor.
